POWDER-DUSTING M'ACHINE.

Application filed November 2, 1922.

a device of this character wherein a verti-' cally disposed and reciprocated rod is operated by a ground engaging ratchet wheel, said rod supporting receptacles from which poisoned powder is sifted and means whereby the powder receptacles may be adjusted angularly in a horizontal plane in relation to the rows of plants on each side of the machine, thereby insuring the depositing of all of the powder on the rows of plants.

A further object is to provide means whereby the powder receptacles may be ad justed upwardly or downwardly according to the height of the plants.

A further object is to dispose of the ratchet wheel and the powder receptacles adjacent the rear end of the machine, thereby allowing the operator to easily control the machine.

A further object is to provide the rear end of the beam with a downwardly extending spring scraper arm, which arm engages the tread of the ratchet wheel and thoroughly scrapes the same immediately behind the ratchet wheel engaging roller, thereby insuring a positive j olting action as the roller is forced from the top of the ratchet teeth to the bottoms of adjacent ratchet teeth under the influence of a spring.

A further object is to make the high portions of the ratchet teeth relatively wide by outwardly extending members thereby increasing the traction of the ratchet wheel and preventing sliding thereof as the machine is pulled forwardly by draft animals.

A further object is to provide the forward end of the beam with spaced support ing wheels, which wheels support the device when standing still.

With the above and other objects in vie w the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and Serial No. 598,528.

claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing:-

Figure 1 is a side elevation of the power dusting machine.

Figure 2 is a top plan view of the dusting machine.

Figure 3 is a vertical transverse sectional view taken on line 33 of Figure 1, showing one of the powder dusting receptacles in elevation.

Figure 4c is a side elevation of a portion of the ratchet wheel showing a portion of the j olting spring and j olting rod.

Referring to the drawings, the numeral 1 designates a horizontally disposed beam, on which beam is disposed a receptacle 2 for the reception of surplus powder. The forward end 3 of the beam is provided with a clevis 3 to which draft animals may be attached for moving the machine in the direction of the arrow at between rows of plants. Extending downwardly from the forward end 3 of the beam 1 is a bracket 4:, the lower end of which is provided with a transversely disposed axle 5. .Rotatably mounted on the ends of the axle 5 are ground engaging wheels 6, which wheels are primarily designed for supporting the machine when standing still and not in use, however during the operation of the machine they assist in balancing the machine by engagement with the ground.

Extending downwardly from the rear end 7 of the beam 1 are brackets 8 located on opposite sides of the beam, which brackets are connected together at their lower ends by the bolt 9, on which bolt the ground en-.

gaging ratchet wheel 10 rotates in the direction of the arrow 6 when the device is in operation. The ratchet wheel 10 has the high portions 11 of its teeth 12 considerably wider than the ratchet wheel thereby increasing the traction of the wheel, preventing sliding of the wheel during the advancement of the machine and consequently insuring a positive operation of the jolting operation hereinafter set forth, and at the same time reducing the weight of the machine to a minimum.- Extending downwardly from the rear end of the beam 1 is a spring arm 13, which arm terminates in an angularly disposed scraper 14: which engages the tread of the ratchet and scrapes dirt therefrom, before the teeth reach the roller 15, which is carried by the leaf spring 16 and is forced downwardly into engagement with the ratchet teeth. As the roller drops or is forced from the top of one ratchet tooth to the bottom of the adjacent ratchet tooth impact is formed, which impact is positive for the reason that the teeth are thoroughly cleaned by the scraper 14, consequently the vertically disposed jolting rod 17, which rests on the free end of the spring 16 is given a positive jolting action at the bot tom of its reciprocating movement. The jolting rod 17 extends upwardly through the beam 1 between anti-frictional rollers 18 carried by the beam, and consequently is positively jolted by the sudden stopping thereof when the roller 15 drops to the adjacent ratchet tooth. The lower end of the jolting rod 17 rests on the upper side of the spring 16, however it is preferably disposed adjacent the roller 15 to insure a positive jolting operation as distinguished from a spring one if the rod engaged the spring 16 at a pointspaccd from the roller 15.

Extending transversely of the machine above the beam 1, and attached to the jolting rod 17 are spaced rods 19, which rods pass between clamping plates 20 carried by the jolting rod. Clamping plates 20 are securely clamped together and to a clamp- J ing plate 21 by means of bolts 22, and it is obvious that by loosening the bolts the rods 19 may be adjusted upwardly or downwardly for positioning the powder dusting receptacle 23 at various distances above ad jacent rows of plants, on which powder is to be dusted, thereby accommodating the machine to various heights of plants. EX- tending between the plates 24 are vertically disposed rods 25, which are held by said plates after they have been adjusted to a desired vertical position according to the heights of the plants. Plates 24 in combina tion with the plates 25 which are clamped on the rods 19 form clamping means where by the receptacles 23 are supported at various distances above the plants and at the same time form means whereby the receptacle may be adjusted in various positions in a horizontal plane according to the spread of the plants as clearly shown in dotted lines in Figure 2, thereby allowing all of the dusted material from the receptacle 23 to be deposited on the plants and the waste of material reduced to a minimum.-

The .lower ends of the rods 25 extend downwardly between spaced partitions 27 in the receptacles 26, which partitions divide the receptacles into spaced compartments 28, either one of which may be used or both if so desired. The bottoms of the receptacle are provided with screens 29, through which the powder is jolted by the jolting action of the jolting rod 17. Rods 15 are secured to the receptacles by nuts 30.

From the above it will be seen that a powder dusting machine is provided, which machine is simple in construction, positive in operation, and one wherein the receptacles 23 may be adjusted vertically accord ing to the height of the plant, and also in a horizontal plane for adjusting the receptacles to register with the width of various rows of plants, thereby preventing waste of material by dusting the same between the rows of plants. 1

The invention having been set forth what is claimed as new and useful is A powder dusting machine, said machine comprising a beam, draft attaching means at the forward end of the beam, a vertically movable rod extending through the rear end of the beam and adapted to reciprocate, a

leaf spring secured to the beam and having its free end disposed beneath the lower on of the vertically movable rod, powder receiving receptacles supported by the vertically movable rod, a roller carried by the free end of the spring, and a ratchet wheel disposed beneath the roller and with which the roller engages.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
